Specification of Letters Patent.

Application filed February 12, 1914. Serial 818,243.

of Massachusetts, have invented certain 'new and useful Improvements in F orm-Holding Means for Sole-Pressing Machines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to form holding devices for sole pressing or sole leveling machines.

The object of the invention is to provide novel and improved means for positioning and securing the form upon its carrier which will enable the adjustments requisite to the accurate positioning of the form to be quickly and conveniently made, and which will firmly secure the form to the carrier while permitting it to-be readily removed and replaced. To these ends the invention consists in the features of construction and combinations of parts hereinafter described and referred to in the claims, the advantages of which will be obvious to those skilled in the art from the following detailed description of the embodiment of the invention shown in the drawings.

In the drawings, Figure 1 is a side elevation of a form carrier and form embodying the invention in its preferred form; Fig. 2 is an end elevation looking toward the left in Fig. 1; Fig. 3 is a vertical sectional view on line 33, Fig. 1; Fig. 4 is a plan view and Fig. 5 is a plan view of the form detached from its carrier.

In the drawings the invention is shown as embodied in a form carrier and form adapted for use in sole pressing machines of the type shown and described in the patent to Mayo, No. 861,746, June30, 1907, in which the sole of a shoe is subjected to a rolling pressure between the last upon which the shoe is supported and a cooperating sole pressing form. As shown, the form 2 is removably supported on a carrier 4 formed on the lower end of a plunger 6 by which the carrier is mounted on the swinging carrier-arm of the machine in the usual manner. The devices for positioning and securing the form on the carrier are constructed and arranged to secure the various adjustments requisite for accurately positioning the form to cooperate properly with the shoe supporting last, and in order that the adjustments more frequently required may be accurately and quickly made, thepositioning devices for securing these adjustments are so arranged that they are accessible while the form is supported on the carrier. By manipulation of the positioning and securing devices, the form may be adjustedi with relation to the carrier either longitudinally or laterally, may be tilted either longitudinally or laterally, or may be swung laterally to bring its medial line into line with the medial line of the last. The form maytherefore be accurately positioned to cooperate properly and efficiently with the last in pressing and shaping the shoe sole.

In I the construction shown the form is secured to the carried by four clamping and positioning bolts 8, 10, 12 and 14 mounted on the carrier in position to engage opposite sides of a longitudinal rib 16 projecting from'the upper side of the form. One or both'sides of the rib are inclined inwardly to provide inclined surfaces for engagement with the securing bolts, so that the bolts will tend to draw the form toward the carrier when they are forced against the opposite sides of the rib. The vertical position of the form with relation to the under side of the carrier is determined by four positioning stop bolts 18 which are screwed into the upperside of the form, and are arranged to engage the under side of the carrier on opposite sides: of the rib 16 and of the medial line of the form. When the clamping bolts are tightened, the heads of the stop bolts 18 are drawn firmly against the under'face ofthe carrier, and determine the position of the face of the form with relation to thecarrier. By adjustment of thestop bolts 18 the face of the form may justments rapidly and accurately. By manipulation of the securing bolts 8, 10, 12 and 14, the form may be adjusted'laterally, or may be swung laterally to'bring-t-he'me dial line of the form into proper relation to the medial line of the last. These adjustments may alsobe made while the form is in position on the carrier, so that it may be brought into cooperating relation with the last in'making the adjustments. The longitudinal position of the form is determined by a positioning stop bolt which is screwed into the rearend of the rib 16 and engages a stop-formed by the rear end 22 of adove-tailed groove 2a which is formed in the'under side of the carrier to receive therib. I

Thezopposedfa'ces of the rib 16 which are engaged by the opposed. bolts 8-and 10 and the opposed-bolts '12 and 14, may be inwardlyinclined to cooperate with the bolts in'drawing the form firmly against the underside ofthe carrier. It is preferred, however,'to-:'provide verticahbearing surfaces 26 on one side of'the rib-to cooperate with the boltsl0 and-Mat that side in positioning the form laterally. 'With this construction thebolts 10 and 14 may beadjusted to properly position the form laterally, and the bolts 8 and '12 be manipulated in securing and releasing the form. The ends of the bolts 10 and lt-willcooperate with the vertical sur faces 26 to'm-aintain the form-in position as it is=drawn toward the carrier .bythe tightening of thebolts 8 and 12. ln-order that the 'form may'be readily withdrawn from the carrier when-the bolts 8 and 12' are loosened, the side*of the rib 16 is under cut at 28, as indicatedby'dotted lines in Fig. 5 to pass longitudinally over the ends of the bolts '10- and 14.

' In order that-the carrier may beused to support =forms provided with the securing and @positiOning screws indicated in Fig. 1 of the patent to' Mayo above referred to, the carrier may be provided at its'rear end with a grooved plate 30, and a second grooved plate indicated in dotted-lines at 32 inFig. l-may be temporarilysecured on the front end -of the carrier =.by 'the' bolts 34. The plates correspond to 'theplates on the form carrier which are en'gagedby the screws'on the form indicated-in-Fig. lof the Mayo patent.

- While it is preferred 'to employ the speci-fic construction and arrangement of parts shown and described,- it will be understood that this construction and "arrangement is not 'essentialto the broader features of the invention, andmay be varied andmod-ified asfounddesirable'or best suited to the machine in'which the invention is tobe embodied;

Having explained-the nature and object of the invention, and'specifically described one form of mechanism in which it may be emmachines having, in combination, 'aform carrier, a form,"a longitudinal rib 'o'n'one of said parts, and two sets of opposed securing bolts on the other part engaging opposite sides of the rib and spaced longitudinally a sufiicient distance to securean"an'gular adjustment of the form relative to the carrier when the securing bolts are relatively adjusted.
